Fear is an instinctive, involuntary emotion that is experienced by every individual, whether it is fear of a situation, a person or an animate object. Fear is the body's response to prevent danger and pain when such stimuli are plausible.

Fear of snakes allowed the hunter-gatherers to dodge venomous snake bites, allowing potential mate selection and reproduction in the future. Fear of a situation could potentially be maladaptive because it may cause an individual to not want to leave their comfort zone and meet new people, decreasing their chances of mate selection and reproduction. In all aspects, fear warns ourselves of potential danger and harm, allowing us to better survive and reproduce.
